diffusion coefficient see diffusion coefficient. coefficient of digestibility the proportion of a food that is digested compared to what is absorbed, expressed as a percentage. dilution coefficient a number that expresses the effectiveness of a disinfectant for a given organism.
Best Answer: the rate of diffusion is directly proportional to the concentration gradient. The greater the difference in concentration between two areas, the greater the rate of diffusion. Thus, when the gradient is zero, there will be no net diffusion, diffusion will only occur so long as a concentration gradient exists; the rate of diffusion is indirectly proportional to resistance.
